Warmth from the depth: Geothermal project starts in Lower Lusatia!

Warmth from the depth: Geothermal project starts in Lower Lusatia!

A hot topic in Brandenburg: The use of geothermal energy is the focus of regional energy policy. As Cityreport , a geological admission between Cottbus and Guben will be carried out in the late autumn 2025 to examine the depth geothermal energy in more detail. Today, on July 7, 2025, the preparatory studies begin, which should create important foundations for the heat supply of the region in the coming weeks.

The Brandenburg government has commissioned the State Office of Geology and Raw Materials (LBGR) to a comprehensive seismic campaign, which aims at possible water-bearing, hot layers-also called aquiferen. Economic and Energy Minister Prof. Dr.-Ing. Jörg Steinbach emphasizes that geothermal energy plays a central role in the efforts of sustainable, safe and affordable heat supply. "The geothermal potential must be used better," explains Steinbach. The ministry promotes this initiative with 3 million euros.

geothermal energy - a way to a sustainable future

What's behind the geothermal energy? This form of energy generation uses the heat stored in the earth's surface and has many advantages: it is regionally available, reliable and climate -neutral. Above all, the deep geothermal energy, which uses water -bearing layers from around 1,000 meters, is considered a regenerative and base load capable heat source, which can be integrated into the heating networks and industrial processes. The detailed knowledge of the geological structures in Brandenburg, however, have so far been insufficient in order to make reliable statements about geothermal use, so Lbgr .

As part of the upcoming campaign, a seismic 2D exploration is carried out, in which artificially generated seismic waves are guided by layers of earth in order to draw conclusions on their properties. For this purpose, geophones are installed on the earth's surface that record the reflected waves. This analysis will provide important information to determine the best locations for future geothermal atomic projects. The route of the seismic exploration will be over 100 kilometers long.

projects and potential in the region

already tried and tested geothermal atomic projects in Brandenburg show the great potential of this technology. Differences are made in the near -surface and the depth of geothermal energy. In Brandenburg, over 71,238 heat pumps are already in use, and projects such as the geothermal heating center in Prenzlau set new standards by promoting hot water from over 1,000 meters to cover the heat requirement of the region. These projects illustrate how important it is to better understand the local conditions in order to efficiently use these heat sources.

The current seismic explorations should not only expand the basics of geothermal energy, but also create planning security for municipalities and industry. Economic Minister Daniel Keller emphasizes the support of municipal heat planning as part of these measures. By obtaining necessary permits and coordination processes with cable operators for drinking and wastewater as well as gas, electricity and oil, it is ensured that all interests of the public and the infrastructure are taken into account.

In autumn 2025, information events for residents along the SeismiK route are also planned to include the population in this important process. By using geothermal energy, Brandenburg could not only replace fossil fuels, but also become more independent of energy imports. This is how preparations for an environmentally friendly and future -proof energy supply are in full swing, such as mwaek . It remains exciting how the developments around the geothermal energy will develop in the coming years.
